Boktai 2: Solar Boy Django is an action role-playing video game for the GBA, developed and published by Konami in 2005. It is the sequel to Boktai: The Sun Is in Your Hand. Much like its predecessor, the GBA cartridge features a physical solar sensor to detect ultraviolet radiation with the idea that you would use the power of the sun to help you play through the game, with none of the game's mechanics being tuned for having access to max sunlight. For this run, the UV inputs are done internally in mGBA.
Drakodan gets inordinately lucky with the items that drop from enemies before forging an impossible sword and going underground to kill an immortal snake, completing the run in record time.
